My dentist just recommended I use a fluoride mouth rinse, as I have 3 small areas on my teeth that need to be cleaned and covered with amalgam (not silver, thank you!) filling stuff. I use a SonicCare toothbrush, a natural toothpaste with tea tree oil in it (by Desert Essence), am faithful about flossing, don't drink soda or eat much sugar, so I guess I can blame this on the extreme stresses I've dealt with this summer. sigh. So, what's the scoop on fluoride? I'm not sure I've read anything good about it. thanks, Beth.
